Those all great answers, you came up with. One of my friends teenagers, would go to the airport and take the luggage carts back, for the 25 cents deposit. They made $12.00 or more. When it was raining, this one guy would sell umbrellas, to passengers, just getting there. He'd get the umbrellas at places like dollar stores, or Biglots. He'd sell them for about $5.00. I had a friend, during the holidays, who would sell cupcakes at the mall. She'd ask for permission and they would let her, sometimes they charge. There are countless ways. I knew guys, who lost their jobs, and gave rides to people they know. They didn't charge that much. It got them groceries, and gas money.
